An article gripper has two cantilevered jaws biased together by a spring assembly to hold an article between arcuate surfaces of the jaws. The jaws are cantilever-mounted from respective pivot pins, and the article enters radially through an opening formed between the outboard ends of the cantilevered jaws. Between the pivot pins and the gripped article, the jaws have interengaging teeth which permit ease of engagement and disengagement as the jaws are pivoted, yet the teeth prevent unwanted sliding movement of one jaw past the other, as an article is located within the jaws.
